Product Overview: The H 319 Adapter Sleeve
The H 319 Adapter Sleeve is a fundamental component used for mounting bearings with a tapered bore onto a cylindrical shaft with a 95mm diameter. As a key part of our H 300 Series, this adapter sleeve provides a simple, reliable, and cost-effective method for securing bearings, ensuring a tight fit and correct positioning without the need for special shaft machining. This assembly, which includes the H 319 sleeve, a corresponding lock nut, and a lock washer, simplifies both installation and dismounting processes, making it a popular choice in a wide array of industrial applications.
Our H 319 sleeves are manufactured to precise industry standards, ensuring full interchangeability and performance. They are essential Bearing Accessories that enable the use of standard commercial shafts, reducing overall assembly costs. By using an adapter sleeve, bearings can be easily positioned anywhere along the shaft, providing flexibility in machine design and maintenance.

Key Features of the H 319 Sleeve
- Simplified Mounting: Allows bearings with a tapered bore to be mounted on smooth or stepped cylindrical shafts easily.
- Complete Assembly: Typically used with a KM 19 lock nut and an MB 19 lock washer (sold separately) to securely lock the bearing in place.
- Tapered Design: Features a tapered outer surface that matches the bearing's inner ring bore, ensuring a solid interference fit when tightened.
- Slotted Construction: The sleeve is slotted, allowing it to contract and grip the shaft firmly as the lock nut is tightened.
- High-Quality Material: Constructed from durable steel to withstand high mounting forces and provide long-term operational reliability.
- Positional Flexibility: Enables the bearing to be located at any position along the shaft, offering versatility in machine assembly.
Common Applications
- Industrial Fans and Blowers: Used to mount bearings on motor shafts, ensuring stable and efficient fan operation.
- Conveyor Systems: Secures bearings on conveyor rollers and drive shafts, facilitating smooth material transport.
- Agricultural Machinery: Applied in equipment like combines, balers, and tillers where robust bearing mounting is critical.
- Pumps and Compressors: Provides a reliable method for fixing bearings in various types of industrial pumps and gearboxes.
